Kim Kardashian and Kanye West welcomed their third child earlier this week.

And some fans are convinced that Kylie Jenner was her sister's surrogate in a bizarre conspiracy theory.

It comes after Kim announced the arrival of a "healthy" baby girl, who was born at 12:47am on January 15 weighing 7lb 6oz via a surrogate, according to the Daily Mail.

The theory comes after Twitter was set alight on Friday with a wild rumour Kylie was "in labour" and rushed to hospital.


While Kylie has yet to respond to reports that she is expecting her first child with boyfriend Travis Scott, fans were quick to jump to the conclusion that she was in fact acting as Kim's surrogate.

The speculation she was in labour began on a Facebook fan page called The Morning Breathers in which a member posted a screenshot of an alleged conversation with a friend who apparently works at the hospital according to Clevver.

In the image posted in the community, the alleged insider claimed that the 20-year-old star checked into the medical facility and was in labour.

However TMZ later confirmed the reports were a false alarm.

But fans took to Twitter to discuss the conspiracy theory, picking up on the false rumours the make-up guru was in hospital.

MailOnline has contacted Kylie Jenner's representatives for comment.

Meanwhile, Kim, 37, announced the news in a message on her website titled, "She's here! We're so in love."

She wrote: "Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl.

"We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care. North and Saint are especially thrilled to welcome their baby sister. Love, Kim Kardashian West."

Kim and Kanye were both in the delivery room with the surrogate, although the rapper was behind a curtain until after the baby was born, according to TMZ .

Kim was the first person to hold the baby girl for skin-to-skin bonding, but the surrogate was allowed some contact with the child after the birth.

Her sisters Kourtney, Khloe and mother Kris were also at Cedars-Sinai Medical Center in L.A., where the family's doctor Dr. Paul Crane oversaw the delivery.

Their decision to go through a surrogate for their third child came after Kim suffered complications with her two pregnancies, experiencing early-onset preeclampsia with North, four, and further troubles during labor with Saint, two.

Kim previously admitted that she's found the surrogacy experience to be very stressful.

She shared: "Anyone that says or thinks it is just the easy way out is just completely wrong. I think it is so much harder to go through it this way, because you are not really in control.

"And, you know, obviously you pick someone that you completely trust and that you have a good bond and relationship with, but ... knowing that I was able to carry my first two babies and not my baby now, it's hard for me.

"So, it's definitely a harder experience than I anticipated just in the control area."

She also admitted she had trouble explaining the process to her children.

She chose not to invite the surrogate to her lavish baby shower in November to avoid confusing her little ones.

Kim said at the time:"'I, um, I did not [invite the surrogate]. I did introduce her to my family. I introduced her to my family earlier that day. And, you know, I just thought, I don't know, it was like a weird decision to have to make.

"Of course, I would've wanted her to be there and be a part of it, but I hadn't really gone that far in explaining it to my kids yet.

"So I have to figure that out first before they really see and then if we're celebrating, you know, her, I just want to celebrate the baby. I think I have to explain it to my kids first and figure out how I'm going to explain it to them."

Kim and Kanye started dating in 2012 shortly after the end of her 72-day marriage to Kris Humphries. They wed in 2014 in a lavish ceremony in Italy.

Their relationship hit a rough patch after they both endured a traumatic end to 2016, with Kim being robbed at gunpoint in Paris, France, in October, and the Famous rapper being hospitalised after suffering a breakdown just one month later.
